With a BMI of 26.1, you're above 33% of men in United States.

Estimated BMI distribution of U.S. adults by sex. The green band is the healthy range; the line marks your current BMI.

Formulas use international (WHO) standards — healthy ranges are the same worldwide; only the units differ. The national context below uses U.S. data (CDC / NHANES).

Weight in the United States

There’s no single “ideal” weight, but seeing where you fall against the population helps put your number in context. These figures come from the CDC’s NHANES survey.

Why “ideal weight” is a range

Ideal weight isn’t a single magic number — it’s a band of healthy weights for your height, where weight-related health risk is, on average, lowest.

VitaDup shows that band two ways: from the healthy BMI range (18.5–24.9) applied to your height, and from the classic clinical formulas (Devine, Robinson, Miller, Hamwi). Use it as a guide, not an exact target.

What to keep in mind

These tools are screens, not diagnoses. They don’t distinguish muscle from fat or show where fat is stored — a key risk factor.

Pair your result with waist measurements and body-fat percentage, and with a healthcare professional’s view.

Frequently asked questions

Is ideal weight different in the U.S. than elsewhere?

The healthy-weight formula depends on your height and sex, not your country. What changes is the percentile — how you compare to U.S. adults.

Why is my percentile high at a healthy weight?

Because most U.S. adults are above the healthy range, so a healthy weight can sit below the national average.

What if I’m very muscular?

BMI-based ranges can overstate fat for muscular people. Body-fat percentage is a better reference there.
